GENEVA (AP) — High-ranking officials representing 46 countries including the U.S., China and European Union nations have failed to agree on a list of "environmental goods" like solar-powered air conditioners or LED light bulbs that could be targeted for lower tariffs.

The two-day meeting at World Trade Organization involved a bid to agree on reducing tariffs on over 200 environment-friendly goods worth more than $1 trillion in trade annually.

Diplomats cited troubles over Chinese demands on many goods including bicycles, and disagreements over sustainable-development lumber between Canada and New Zealand on one side and Japan and Taiwan on another.

Any agreement would only be a first step. The incoming administration of U.S. president-elect Donald Trump is expected to have important say on the final contours of the Environmental Goods Agreement.
